Dear All,

I have to qualify two welding procedures involving following base materials

1)one WPS for A995 GR 4A (UNASSIGNED) to A182 F51 (P No. 10 H Gr 1)

2)one WPS for A995 GR 4A (UNASSIGNED) to A995 GR 4A (UNASSIGNED)

Are both WPS qualified by a PQR in which base materials are
A995 GR 4A (UNASSIGNED) to A240 UNS S31803 (P No. 10 H Gr 1)?

Thank you for your help

Marco

RE: P no. qualified

Marco,
You should be posting in the ASME section.
The answer to your question is no, you will require two PQRs (QW 424),
Regards,
Kiwi
